Rihanna announces 777 world tour

Rihanna is taking a lucky group of fans and journalists along for the ride when she kicks off her '777' world tour this week (14.11.12).

Rihanna will play seven gigs across seven countries during her '777' world tour.

The 'Diamonds' hitmaker has invited a group of fans and members of the press to join her for a ''rock 'n' roll adventure'' aboard her tour bus to promote her seventh studio album, 'Unapologetic'.

Rihanna explained: ''I am so excited about the '777' tour. We are turning this jumbo jet into our tour bus. We are practically living on this thing for a week: sleeping, partying all together. Me, my fans, the press... it's going to be a wild ride.''

''I wanted it to be a rock 'n' roll adventure, and I think when it's over it will be the coolest thing I've ever done. I'm that excited about it.''

The provocative star - who insists she is just ''friends'' with her ex-boyfriend Chris Brown - will be visiting the capital cities of France, Germany, Sweden, the USA, Mexico, Canada and the UK and taking a lucky group of fans and 150 journalists representing 82 countries along for the ride.

However, the 24-year-old singer has yet to reveal the exact venues - despite the top secret tour kicking off tomorrow (14.11.12).

She tweeted: ''This is really going down huh?!! This was once a random idea thrown out in a brainstorm...coincidentally, on a plane!! Whoever is getting on my flying tour bus with us, Good Luck!!! (sic)''
